[Numpy-discussion] Scons and numpy, second milestone: all numpy built with scons.

[Albert Strasheim]

Hello

Firstly, great work. I always thought SCons was the way to go for
NumPy and SciPy, and you've pulled it off.

I don't think you should make the autodetection of BLAS and LAPACK too
auto. A .cfg file like mpi4py's mpi.cfg (almost like NumPy's site.cfg,
but simpler) would be great. This way, you can provide a few default
build configurations for common platforms, but still make it easy for
people to configure their build exactly the way they want it, if they
so choose.

Cheers,

Albert
